Estudio geotécnico in Aracena

In Aracena, materials such as slates and schists predominate, accompanied to a lesser extent by granite, gneiss and other igneous rocks. These substrate types are characterised by high geotechnical competence and generally exhibit low permeability, which can limit the accumulation of water at depth but favour the presence of sporadic superficial aquifers. The bearing capacity of these soils is usually favourable for shallow foundations, enabling efficient structural solutions, although the hardness of the rock may require specialised excavation techniques.

Seismicity in the area is moderate, with 22 events over the last 30 years and a maximum recorded magnitude of 3.1, which implies reduced seismic risk in the context of structural design. No risk of expansivity is detected, as the substrate is not clayey. However, the presence of karstic phenomena is significant, so it is essential to carry out a specific verification of the existence of cavities before designing the foundation, making this aspect the top geotechnical constraint in Aracena.
